With continued reference to FIG. 1, proximity sensor may include projected capacitive touch (PCT) technology, which is a capacitive technology which allows more accurate and flexible operation, by etching the conductive layer. A grid may be formed either by etching one layer to form a grid pattern of electrodes, or by etching two separate, parallel layers of conductive material with perpendicular lines or tracks to form the grid; comparable to the pixel grid found in many liquid crystal displays (LCD). The greater resolution of PCT allows operation with no direct contact, such that the conducting layers can be coated with further protective insulating layers, and operate even under screen protectors, or behind weather and vandal-proof glass. Because a top layer of a PCT may be composed of glass, PCT may represent a more robust solution versus resistive touch technology. PCT may include a self-capacitance and/or mutual capacitance. For the purposes of this disclosure, “mutual capacitive” sensors have a capacitor at each intersection of each row and each column. Proximity sensor may also be used to detect machine vibration monitoring to measure the variation in distance between a shaft and its support bearing or any two or more elements included by plurality of energy storage elements 108. Proximity sensor may include a photoelectric sensor. A photoelectric sensor may be a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared and a photoelectric receiver.

With continued reference to FIG. 1, proximity sensor may include opposed (through-beam), retro-reflective, and proximity-sensing (diffused) types of proximity sensors. A through-beam arrangement may consist of a receiver located within the line-of-sight of the transmitter. In this mode, an object may be detected when the light beam is blocked from getting to the receiver from the transmitter. A retroreflective arrangement may place the transmitter and receiver at the same location and uses a reflector to bounce the inverted light beam back from the transmitter to the receiver. An object may be sensed when the beam is interrupted and fails to reach the receiver. A proximity-sensing (diffused) arrangement may be one in which the transmitted radiation must reflect off the object in order to reach the receiver. In this mode, an object is detected when the receiver sees the transmitted source rather than when it fails to see it. As in retro-reflective sensors, diffuse sensor emitters and receivers may be located in the same housing. But the target acts as the reflector so that detection of light is reflected off the disturbance object. The emitter may send out a beam of light (most often a pulsed infrared, visible red, or laser) that diffuses in all directions, filling a detection area. The target may then enter the area and deflects part of the beam back to the receiver. Detection occurs and output is turned on or off when sufficient light falls on the receiver. Some photo-eyes have two different operational types, light operate and dark operate. The light operates photo eyes become operational when the receiver “receives” the transmitter signal. Dark operate photo eyes become operational when the receiver “does not receive” the transmitter signal. The detecting range of a photoelectric sensor may be its “field of view”, or the maximum distance from which the sensor can retrieve information, minus the minimum distance. A minimum detectable object is the smallest object the sensor can detect.

With continued reference to FIG. 1, proximity sensor may include an electromagnetic induction sensor configured to use the principle of electromagnetic induction to detect or measure objects. An inductor develops a magnetic field when a current flows through it; alternatively, a current will flow through a circuit containing an inductor when the magnetic field through it changes. This effect can be used to detect metallic objects that interact with a magnetic field. Nonmetallic substances such as liquids or some kinds of dirt do not interact with the magnetic field, so an inductive sensor can operate in wet or dirty conditions which may arise in or on plurality of energy storage elements 108.

With continued reference to FIG. 1, at least a sensor 128 may include a load cell. A load cell may be a force transducer. It may convert a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. At least a sensor 128 may, in a load cell embodiment measure the force of one or more expanding or contracting elements included by plurality of energy storage elements 108. As the force applied to the load cell increases, the electrical signal changes proportionally. Load cell may be strain gauges, pneumatic, and hydraulic, and in non-limiting embodiments, at least a sensor 128 may include these or other nondisclosed sensors alone or in combination.

Referring now to FIG. 1, at least a sensor 128 may include a plurality of sensors in the form of individual sensors or a sensor suite working in tandem or individually. A sensor suite may include a plurality of independent sensors, as described in this disclosure, where any number of the described sensors may be used to detect any number of physical or electrical quantities associated with an aircraft power system or an electrical energy storage system. Independent sensors may include separate sensors measuring physical or electrical quantities that may be powered by and/or in communication with circuits independently, where each may signal sensor output to a control circuit such as a user graphical interface. In a non-limiting example, there may be four independent sensors housed in and/or on battery module 500 measuring temperature, electrical characteristic such as voltage, amperage, resistance, or impedance, proximity, or any other parameters and/or quantities as described in this disclosure. In an embodiment, use of a plurality of independent sensors may result in redundancy configured to employ more than one sensor that measures the same phenomenon, those sensors being of the same type, a combination of, or another type of sensor not disclosed, so that in the event one sensor fails, the ability of system 100 and/or user to detect phenomenon is maintained and in a non-limiting example, a user alter aircraft usage pursuant to sensor readings.

With continued reference to FIG. 1, at least a sensor 128 may include electrical sensors.

Detection of a charge reduction event may include detection of a temperature, of the cell above a threshold level, detection of a voltage and/or resistance level above or below a threshold, or the like.

With continued reference to FIG. 1, at least a sensor 128 may include a sensor configured to detect gas that may be emitted during or after a cell failure. “Cell failure”, for the purposes of this disclosure, refers to a malfunction of a battery cell, which may be an electrochemical cell, that renders the cell inoperable for its designed function, namely providing electrical energy to at least a portion of an electric aircraft. Byproducts of cell failure may include gaseous discharge including oxygen, hydrogen, carbon dioxide, methane, carbon monoxide, a combination thereof, or another undisclosed gas, alone or in combination.

At least a sensor 128 may measure voltage at an instant, over a period of time, or periodically. At least a sensor 128 may be configured to operate at any of these detection modes, switch between modes, or simultaneous measure in more than one mode. First battery management component may detect through at least a sensor 128 events where voltage nears the lower voltage threshold. The lower voltage threshold may indicate power loss to or from an individual battery cell or portion of the battery pack. First battery management component may detect through at least a sensor 128 events where voltage exceeds the upper and lower voltage threshold. Events where voltage exceeds the upper and lower voltage threshold may indicate battery cell failure or electrical anomalies that could lead to potentially dangerous situations for aircraft and personnel that may be present in or near its operation.

With continued reference to FIG. 1, one or more sensors including at least a sensor 128 may be communicatively connected to at least a pilot control, the manipulation of which, may constitute at least an aircraft command. “Communicative connecting”, for the purposes of this disclosure, refers to two or more components electrically, or otherwise connected and configured to transmit and receive signals from one another.

One of ordinary skill in the art would appreciate, after reviewing the entirety of this disclosure, that motion may include a plurality of types including but not limited to: spinning, rotating, oscillating, gyrating, jumping, sliding, reciprocating, or the like. At least a sensor may include, torque sensor, gyroscope, accelerometer, torque sensor, magnetometer, inertial measurement unit (IMU), pressure sensor, force sensor, proximity sensor, displacement sensor, vibration sensor, among others.

For example, in a non-limiting embodiment, sensor suite may include a plurality of accelerometers, a mixture of accelerometers and gyroscopes, or a mixture of an accelerometer, gyroscope, and torque sensor.

With continued reference to FIG. 1, any of the sensors described in this disclosure may be included within a sense board, wherein the sense board may include sensors configured to measure physical and/or electrical parameters, such as without limitation temperature and/or voltage, of one or more the battery cells. Sense board and/or a control circuit incorporated therein and/or communicatively connected thereto, may further be configured to detect failure within each battery cell, for instance and without limitation as a function of and/or using detected physical and/or electrical parameters. Cell failure may be characterized by a spike in temperature and sense board may be configured to detect that increase and generate signals, which are discussed further below, to notify users, support personnel, safety personnel, maintainers, operators, emergency personnel, aircraft computers, or a combination thereof. Sense board may include thermocouples, thermistors, thermometers, passive infrared sensors, resistance temperature sensors (RTD's), semiconductor based integrated circuits (IC), a combination thereof or another undisclosed sensor type, alone or in combination. Temperature, for the purposes of this disclosure, and as would be appreciated by someone of ordinary skill in the art, is a measure of the heat energy of a system. Heat energy is, at its core, the measure of kinetic energy of matter present within a system. Temperature, as measured by any number or combinations of sensors present on a sense board, may be measured in Fahrenheit (° F.), Celsius (° C.), Kelvin (° K), or another scale alone or in combination. The temperature measured by sensors may include electrical signals which are transmitted to their appropriate destination wireless or through a wired connection.

Further referring to FIG. 1, a sense board may detect voltage and direct the charging or discharging of individual the battery cells according to charge level; detection may be performed using any suitable component, set of components, and/or mechanism for direct or indirect measurement and/or detection of voltage levels, including without limitation comparators, analog to digital converters, any form of voltmeter, or the like.

Further referring to FIG. 1, system 100 may include one or more computing devices such as a sense board and/or a control circuit incorporated therein and/or communicatively connected thereto may be configured to adjust charge to at least one battery cell of the plurality of the battery cells as a function of the detected parameter; this may include adjustment in charge as a function of detection of a charge reduction event. Alternatively, or additionally, sense board and/or a control circuit incorporated therein and/or communicatively connected thereto may be configured to increase charge to a cell upon detection that a charge reduction event has ceased; for instance, sense board and/or a control circuit incorporated therein and/or communicatively connected thereto may detect that a temperature of a subject battery cell has dropped below a threshold and may increase charge again. Charge may be regulate using any suitable means for regulation of voltage and/or current, including without limitation use of a voltage and/or current regulating component, including one that may be electrically controlled such as a transistor; transistors may include without limitation bipolar junction transistors (BJTs), field effect transistors (FETs), metal oxide field semiconductor field effect transistors (MOSFETs), and/or any other suitable transistor or similar semiconductor element. Voltage and/or current to one or more cells may alternatively or additionally be controlled by thermistor in parallel with a cell that reduces its resistance when a temperature of the cell increases, causing voltage across the cell to drop, and/or by a current shunt or other device that dissipates electrical power, for instance through a resistor.

Still referring to FIG. 1, system 100 may include a high current busbar and integral electrical connections. System 100 may charge individual the battery cells depending on battery cell charge levels. Charging may be balanced throughout the plurality of the battery cells by directing energy through balance resistors by dissipating current through resistors as heat. In this manner, the battery cells may be charged evenly, for example, cells with a lower amount of electrical energy will charge more than the battery cells with a greater amount of energy. Cell charge balancing may be controlled via any means described above for regulation of charge levels, including without limitation metal oxide silicon field effect transistor or a metal oxide semiconductor field effect transistor (MOSFET).

With continued reference to FIG. 1, outputs from any sensors or any other component present within system may be analog or digital. Onboard or remotely located processors can convert those output signals from the sensor suite to a usable form by the destination of those signals. The usable form of output signals from sensors, through processor may be either digital, analog, a combination thereof or an otherwise unstated form. Processing may be configured to trim, offset, or otherwise compensate the outputs of sensor suite. Based on sensor output, the processor can determine the output to send to downstream component. Processor can include signal amplification, operational amplifier (OpAmp), filter, digital/analog conversion, linearization circuit, current-voltage change circuits, resistance change circuits such as Wheatstone Bridge, an error compensator circuit, a combination thereof or otherwise undisclosed components. Any signal as described in this disclosure may be manipulated by one or more computing devices or components thereof. An integrator may include an operational amplifier configured to perform a mathematical operation of integration of a signal; output voltage may be proportional to input voltage integrated over time. An input current may be offset by a negative feedback current flowing in the capacitor, which may be generated by an increase in output voltage of the amplifier. The output voltage may be therefore dependent on the value of input current it has to offset and the inverse of the value of the feedback capacitor. The greater the capacitor value, the less output voltage has to be generated to produce a particular feedback current flow. The input impedance of the circuit may be almost zero because of the Miller effect. Hence all the stray capacitances (the cable capacitance, the amplifier input capacitance, etc.) are virtually grounded and they have no influence on the output signal. An operational amplifier as used in an integrator may be used as part of a positive or negative feedback amplifier or as an adder or subtractor type circuit using just pure resistances in both the input and the feedback loop. As its name implies, the Op-amp Integrator is an operational amplifier circuit that causes the output to respond to changes in the input voltage over time as the op-amp produces an output voltage which may be proportional to the integral of the input voltage. In other words, the magnitude of the output signal may be determined by the length of time a voltage may be present at its input as the current through the feedback loop charges or discharges the capacitor as the required negative feedback occurs through the capacitor. Input voltage may be Vin and represent the input signal to processor such as one or more of input datum and/or attitude error. Output voltage Vout may represent output voltage such as one or more outputs like rate setpoint. When a step voltage, Vin may be firstly applied to the input of an integrating amplifier, the uncharged capacitor C has very little resistance and acts a bit like a short circuit allowing maximum current to flow via the input resistor, Rin as potential difference exists between the two plates. No current flows into the amplifiers input and point X may be a virtual earth resulting in zero output. As the impedance of the capacitor at this point may be very low, the gain ratio of X_(C)/R_(IN) may be also very small giving an overall voltage gain of less than one, (voltage follower circuit). As the feedback capacitor, C begins to charge up due to the influence of the input voltage, its impedance X_(C) slowly increase in proportion to its rate of charge. The capacitor charges up at a rate determined by the RC time constant, (τ) of the series RC network. Negative feedback forces the op-amp to produce an output voltage that maintains a virtual earth at the op-amp's inverting input. Since the capacitor may be connected between the op-amp's inverting input (which may be at virtual ground potential) and the op-amp's output (which may be now negative), the potential voltage, V_(C) developed across the capacitor slowly increases causing the charging current to decrease as the impedance of the capacitor increases. This results in the ratio of X_(C)/Rin increasing producing a linearly increasing ramp output voltage that continues to increase until the capacitor may be fully charged. At this point the capacitor acts as an open circuit, blocking any more flow of DC current. The ratio of feedback capacitor to input resistor (X_(C)/R_(IN)) may be now infinite resulting in infinite gain. The result of this high gain, similar to the op-amps open-loop gain, may be that the output of the amplifier goes into saturation as shown below. (Saturation occurs when the output voltage of the amplifier swings heavily to one voltage supply rail or the other with little or no control in between). The rate at which the output voltage increases (the rate of change) may be determined by the value of the resistor and the capacitor, “RC time constant”. By changing this RC time constant value, either by changing the value of the Capacitor, C or the Resistor, R, the time in which it takes the output voltage to reach saturation can also be changed for example.

With continued reference to FIG. 1, energy datum 132 may include at least an element of data representative of one or more characteristics of at least a portion of plurality of energy storage elements 108. For example, and without limitation, a portion of the plurality of energy storage elements 108 may have been commanded by modulator unit 120 to discharge energy, at least a sensor 128 may then detect energy datum 132 as a function of that discharging associated with the portion of plurality of energy storage elements 132. Energy datum 132 may include a charge datum. For the purposes of this disclosure, a “charge datum” is one or more elements of data related to at least a portion of plurality of energy storage element's 108 state of charge (SoC). For the purposes of this disclosure, “state of charge” is the level of charge of an electric battery relative to its capacity. The units of SoC may be percentage points (0%=empty; 100%=full). An alternative form of the same measure is the depth of discharge (DoD), the inverse of SoC (100%=empty; 0%=full). SoC is normally used when discussing the current state of a battery in use, while DoD is may be often seen when discussing the lifetime of the battery after repeated use. Charge datum may be one or more elements of data related to the charge of a battery configured for use in an electric aircraft. In an EVTOL, for example, SoC for the plurality of energy storage elements 108 may be the equivalent of a fuel gauge in a gasoline powered vehicle. Charge datum may be calculated, adjusted, searched for in a table, retrieved from a database based on one or more detected parameters, or directly detected, among others. In embodiments, the charge datum may be compared to a calculated charge datum. For the purposes of this disclosure, a “calculated charge datum” is one or more elements of data representing the predicted state of charge of at least a portion of an energy storage device, calculated by a computing device as a function of time.

With continued reference to FIG. 1, energy datum 132 may include a health datum. Processor may be configured to generate health datum as a function of status datum corresponding to the at least a portion of plurality of energy storage elements 108. For the purposes of this disclosure, a “health datum” includes one or more elements of data related to the state of health (SoH) of plurality of energy storage elements 108. For the purposes of this disclosure, “state of health” is a figure of merit of the condition of a battery (or a cell, or a battery pack), compared to its ideal conditions. The units of SoH are percent points (100%=the battery's conditions match the battery's specifications). Typically, a battery's SoH will be 100% at the time of manufacture and will decrease over time and use. However, a battery's performance at the time of manufacture may not meet its specifications, in which case its initial SoH will be less than 100%. In exemplary embodiments, one or more elements of system 100 including but not limited to processor 120 may evaluate state of health of the portion of battery corresponding to health datum. Health datum may be compared to a threshold health datum corresponding to the parameter detected to generate said health datum. Health datum may be utilized to determine, by processor, the suitability of plurality of energy storage elements 108 to a given application, such as aircraft flight envelope, mission, cargo capacity, speed, maneuvers, or the like.

With continued reference to FIG. 1, health datum may include a useful life estimate corresponding to plurality of energy storage elements 108. For the purposes of this disclosure, a “useful life estimate” is one or more elements of data indicating a remaining usability of one or more elements of an energy storage device, wherein the usability is a function of whether or not the one or more energy storage elements may be used in performing their designed functions. Useful life estimate may include one or more elements of data related to the remaining use of plurality of energy storage elements 108. Useful life estimate may include a time limit, usage limit, amperage per time parameter, electric parameter, internal resistance, impedance, conductance, capacity, voltage, self-discharge, ability to accept a charge, number of charge-discharge cycles, age of battery, temperature of battery during previous uses, current or future temperature limitations, total energy charged, total energy discharge, or predictions of failures corresponding to plurality of energy storage elements 108. Processor may be configured to select a datum of a plurality of data and utilize the datum to determine charge datum and health datum. Processor may select data collected from one or more sensors described in this disclosure or one or more elements of data input to a system from which processor may retrieve. Processor may be communicatively connected to one or more databases, datastores, lists, matrices, and/or groups that represent and organize data associated with plurality of energy storage elements 108. Processor is configured to transmit the charge datum and health datum to one or more other elements included by system 100 configured to receive one or more elements of data.

With continued reference to FIG. 1, system 100 may include energy datum 132, wherein energy datum 132 may include a performance characteristic. For the purposes of this disclosure, a “performance characteristic” is at least an element of data representative of performance related to at least a portion of an electric aircraft and/or subsystem thereof. For example, and without limitation, performance characteristic may include a measure of efficiency of one or more of plurality of propulsors 104, plurality of energy storage elements 108, any one or more of the components thereof, or another subsystem of electric aircraft. Performance characteristic may include a measure of temperature of one or more components described in this disclosure. Performance characteristic may include a measure of conductivity, impedance, resistivity, capacitance, current, voltage, or another electrical characteristic of plurality of energy storage elements 108. Performance characteristic may include a measure of a predicted value compared to a measured value.

With continued reference to FIG. 1, system 100 may include energy datum 132 which may be utilized to generate at least a performance datum. For the purposes of this disclosure, “performance datum” is at least an element of data representative of the performance of at least a portion of plurality of energy storage elements generated as a function of at least a measured value. For example, and without limitation, performance datum may include a measured level of charge of at least a portion of plurality of energy storage elements 108 compared to a calculated or predicted level of charge. In general, and without limitation, predicted values related to the herein disclosed system may be generated by one or more computing devices, one or more processors, input by a user, input by a pilot, generated as a function of one or more previous flights or operations, or a combination thereof. For example, and without limitation, performance datum may include a measured state of health of at least a portion of plurality of energy storage elements 108 compared to a calculated or predicted state of health. In general, and without limitation, predicted values related to the herein disclosed system may be generated by one or more computing devices, one or more processors, input by a user, input by a pilot, generated as a function of one or more previous flights or operations, or a combination thereof. Performance datum may include configurable elements of data input by a user or a pilot. For example, and without limitation, performance datum may be set before a mission, wherein a pilot or user desires to generate performance datum including total current flowed out of a plurality of energy storage elements 108. One of ordinary skill in the art would appreciate, after reviewing the entirety of this disclosure, the near limitless configurations of data that may be generated as a function of energy datum 132.

With continued reference to FIG. 1, energy datum 132 may be displayed to one or more pilots and or users by display 136. For the purposes of this disclosure, “display” is a device configured to present information to one or more users or computing devices in a perceivable format. Display 136, in nonlimiting embodiments may include audio, visual, tactile, olfactory, or other cues in order to notify a user or computing device of information. In non-limiting examples, display 136 may include a primary flight display (PFD), multi-function display (MFD), heads-up display (HUD), holograph, projection, gauges, audio cues, video cues, data streams, displayed in a pilot's goggles or helmet, and the like. The details of the display layout on a primary flight display can vary enormously, depending on the aircraft, the aircraft's manufacturer, the specific model of PFD, certain settings chosen by the pilot, and various internal options that are selected by the aircraft's owner (i.e., an airline, in the case of a large airliner). However, the great majority of PFDs follow a similar layout convention. The center of the PFD usually contains an attitude indicator (AI), which gives the pilot information about the aircraft's pitch and roll characteristics, and the orientation of the aircraft with respect to the horizon. Unlike a traditional attitude indicator, however, the mechanical gyroscope is not contained within the panel itself but is rather a separate device whose information is simply displayed on the PFD. Attitude indicator is designed to look very much like traditional mechanical AIs. Other information that may or may not appear on or about the attitude indicator can include the stall angle, a runway diagram, ILS localizer and glide-path “needles”, and so on. Unlike mechanical instruments, this information can be dynamically updated as required; the stall angle, for example, can be adjusted in real time to reflect the calculated critical angle of attack of the aircraft in its current configuration (airspeed, etc.). The PFD may also show an indicator of the aircraft's future path (over the next few seconds), as calculated by onboard computers, making it easier for pilots to anticipate aircraft movements and reactions. To the left and right of the attitude indicator are usually the airspeed and altitude indicators, respectively. Airspeed indicator displays the speed of the aircraft in knots, while the altitude indicator displays the aircraft's altitude above mean sea level (AMSL). These measurements are conducted through the aircraft's pitot system, which tracks air pressure measurements. As in the PFD's attitude indicator, these systems are merely displayed data from the underlying mechanical systems, and do not contain any mechanical parts (unlike an aircraft's airspeed indicator and altimeter). Both of these indicators are usually presented as vertical “tapes”, which scroll up and down as altitude and airspeed change. Both indicators may often have “bugs”, that is, indicators that show various important speeds and altitudes, such as V speeds calculated by a flight management system, do-not-exceed speeds for the current configuration, stall speeds, selected altitudes and airspeeds for the autopilot, and so on. At the bottom of the PFD is the heading display, which shows the pilot the magnetic heading of the aircraft. This functions much like a standard magnetic heading indicator, turning as required. Often this part of the display shows not only the current heading, but also the current track (actual path over the ground), rate of turn, current heading setting on the autopilot, and other indicators. Other information displayed on the PFD includes navigational marker information, bugs (to control the autopilot), ILS glideslope indicators, course deviation indicators, altitude indicator QFE settings, and much more. Although the layout of a PFD can be very complex, once a pilot is accustomed to it the PFD can provide an enormous amount of information with a single glance. Any of the herein described PFD layouts or components may display, in whole or in part, energy datum 132, performance datum, performance characteristic, charge datum, and health datum.

With continued reference to FIG. 1, display 136 may include a multi-function display (MFD). An MFD may be a small-screen surrounded by configurable buttons that can be used to display information to the user in numerous configurable ways. An MFD may be configured to display any one or more elements of data energy datum 132, performance datum, performance characteristic, charge datum, health datum, or a combination thereof, among others. Display 136 may be configured to display useful life estimate corresponding to plurality of energy storage elements 108.

Still referring to FIG. 1, system 100 may include a first propulsor element 140 and a second propulsor element 144. A “propulsor element,” as used in this disclosure, is an electronic circuit and/or circuit element powering a propulsor. A propulsor element may include, without limitation, a propulsor motor, a winding in a propulsor motor, such as one of a plurality of stator windings, an inverter, an electromagnetic element, or the like.

Still referring to FIG. 6, an exemplary embodiment of a machine-learning module 600 that may perform one or more machine-learning processes as described in this disclosure may be illustrated. Machine-learning module may perform determinations, classification, and/or analysis steps, methods, processes, or the like as described in this disclosure using machine learning processes. A “machine learning process,” as used in this disclosure, may be a process that automatedly uses training data 604 to generate an algorithm that will be performed by a computing device/module to produce outputs 608 given data provided as inputs 612; this may be in contrast to a non-machine learning software program where the commands to be executed are determined in advance by a user and written in a programming language.

Still referring to FIG. 6, “training data,” as used herein, may be data containing correlations that a machine-learning process may use to model relationships between two or more categories of data elements. For instance, and without limitation, training data 604 may include a plurality of data entries, each entry representing a set of data elements that were recorded, received, and/or generated together; data elements may be correlated by shared existence in a given data entry, by proximity in a given data entry, or the like. Multiple data entries in training data 604 may evince one or more trends in correlations between categories of data elements; for instance, and without limitation, a higher value of a first data element belonging to a first category of data element may tend to correlate to a higher value of a second data element belonging to a second category of data element, indicating a possible proportional or other mathematical relationship linking values belonging to the two categories. Multiple categories of data elements may be related in training data 604 according to various correlations; correlations may indicate causative and/or predictive links between categories of data elements, which may be modeled as relationships such as mathematical relationships by machine-learning processes as described in further detail below. Training data 604 may be formatted and/or organized by categories of data elements, for instance by associating data elements with one or more descriptors corresponding to categories of data elements. As a non-limiting example, training data 604 may include data entered in standardized forms by persons or processes, such that entry of a given data element in a given field in a form may be mapped to one or more descriptors of categories. Elements in training data 604 may be linked to descriptors of categories by tags, tokens, or other data elements; for instance, and without limitation, training data 604 may be provided in fixed-length formats, formats linking positions of data to categories such as comma-separated value (CSV) formats and/or self-describing formats such as extensible markup language (XML), JavaScript Object Notation (JSON), or the like, enabling processes or devices to detect categories of data.

Alternatively, or additionally, and continuing to refer to FIG. 6, training data 604 may include one or more elements that are not categorized; that may be, training data 604 may not be formatted or contain descriptors for some elements of data. Machine-learning algorithms and/or other processes may sort training data 604 according to one or more categorizations using, for instance, natural language processing algorithms, tokenization, detection of correlated values in raw data and the like; categories may be generated using correlation and/or other processing algorithms. As a non-limiting example, in a corpus of text, phrases making up a number “n” of compound words, such as nouns modified by other nouns, may be identified according to a statistically significant prevalence of n-grams containing such words in a particular order; such an n-gram may be categorized as an element of language such as a “word” to be tracked similarly to single words, generating a new category as a result of statistical analysis. Similarly, in a data entry including some textual data, a person's name may be identified by reference to a list, dictionary, or other compendium of terms, permitting ad-hoc categorization by machine-learning algorithms, and/or automated association of data in the data entry with descriptors or into a given format. The ability to categorize data entries automatedly may enable the same training data 604 to be made applicable for two or more distinct machine-learning algorithms as described in further detail below. Training data 604 used by machine-learning module 600 may correlate any input data as described in this disclosure to any output data as described in this disclosure.

Further referring to FIG. 6, training data may be filtered, sorted, and/or selected using one or more supervised and/or unsupervised machine-learning processes and/or models as described in further detail below; such models may include without limitation a training data classifier 616. Training data classifier 616 may include a “classifier,” which as used in this disclosure may be a machine-learning model as defined below, such as a mathematical model, neural net, or program generated by a machine learning algorithm known as a “classification algorithm,” as described in further detail below, that sorts inputs into categories or bins of data, outputting the categories or bins of data and/or labels associated therewith. A classifier may be configured to output at least a datum that labels or otherwise identifies a set of data that are clustered together, found to be close under a distance metric as described below, or the like. Machine-learning module 600 may generate a classifier using a classification algorithm, defined as a processes whereby a computing device and/or any module and/or component operating thereon derives a classifier from training data 604. Classification may be performed using, without limitation, linear classifiers such as without limitation logistic regression and/or naive Bayes classifiers, nearest neighbor classifiers such as k-nearest neighbors classifiers, support vector machines, least squares support vector machines, fisher's linear discriminant, quadratic classifiers, decision trees, boosted trees, random forest classifiers, learning vector quantization, and/or neural network-based classifiers. As a non-limiting example, training data classifier 616 may classify elements of training data to classes of deficiencies, wherein a nourishment deficiency may be categorized to a large deficiency, a medium deficiency, and/or a small deficiency.

Still referring to FIG. 6, machine-learning module 600 may be configured to perform a lazy-learning process 620 and/or protocol, which may alternatively be referred to as a “lazy loading” or “call-when-needed” process and/or protocol, may be a process whereby machine learning may be conducted upon receipt of an input to be converted to an output, by combining the input and training set to derive the algorithm to be used to produce the output on demand. For instance, an initial set of simulations may be performed to cover an initial heuristic and/or “first guess” at an output and/or relationship. As a non-limiting example, an initial heuristic may include a ranking of associations between inputs and elements of training data 604. Heuristic may include selecting some number of highest-ranking associations and/or training data 604 elements. Lazy learning may implement any suitable lazy learning algorithm, including without limitation a K-nearest neighbors algorithm, a lazy naïve Bayes algorithm, or the like; persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various lazy-learning algorithms that may be applied to generate outputs as described in this disclosure, including without limitation lazy learning applications of machine-learning algorithms as described in further detail below.

Alternatively or additionally, and with continued reference to FIG. 6, machine-learning processes as described in this disclosure may be used to generate machine-learning models 624. A “machine-learning model,” as used in this disclosure, may be a mathematical and/or algorithmic representation of a relationship between inputs and outputs, as generated using any machine-learning process including without limitation any process as described above, and stored in memory; an input is submitted to a machine-learning model 624 once created, which generates an output based on the relationship that was derived. For instance, and without limitation, a linear regression model, generated using a linear regression algorithm, may compute a linear combination of input data using coefficients derived during machine-learning processes to calculate an output datum. As a further non-limiting example, a machine-learning model 624 may be generated by creating an artificial neural network, such as a convolutional neural network including an input layer of nodes, one or more intermediate layers, and an output layer of nodes. Connections between nodes may be created via the process of “training” the network, in which elements from a training data 604 set are applied to the input nodes, a suitable training algorithm (such as Levenberg-Marquardt, conjugate gradient, simulated annealing, or other algorithms) is then used to adjust the connections and weights between nodes in adjacent layers of the neural network to produce the desired values at the output nodes. This process may be sometimes referred to as deep learning.

Still referring to FIG. 6, machine-learning algorithms may include at least a supervised machine-learning process 628. At least a supervised machine-learning process 628, as defined herein, include algorithms that receive a training set relating a number of inputs to a number of outputs, and seek to find one or more mathematical relations relating inputs to outputs, where each of the one or more mathematical relations may be optimal according to some criterion specified to the algorithm using some scoring function. For instance, a supervised learning algorithm may include status datum as described above as one or more inputs, charge or health datum as an output, and a scoring function representing a desired form of relationship to be detected between inputs and outputs; scoring function may, for instance, seek to maximize the probability that a given input and/or combination of elements inputs may be associated with a given output to minimize the probability that a given input may be not associated with a given output. Scoring function may be expressed as a risk function representing an “expected loss” of an algorithm relating inputs to outputs, where loss is computed as an error function representing a degree to which a prediction generated by the relation may be incorrect when compared to a given input-output pair provided in training data 604. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various possible variations of at least a supervised machine-learning process 628 that may be used to determine relation between inputs and outputs. Supervised machine-learning processes may include classification algorithms as defined above.

Further referring to FIG. 6, machine learning processes may include at least an unsupervised machine-learning processes 632. An unsupervised machine-learning process, as used herein, is a process that derives inferences in datasets without regard to labels; as a result, an unsupervised machine-learning process may be free to discover any structure, relationship, and/or correlation provided in the data. Unsupervised processes may not require a response variable; unsupervised processes may be used to find interesting patterns and/or inferences between variables, to determine a degree of correlation between two or more variables, or the like.

Still referring to FIG. 6, machine-learning module 600 may be designed and configured to create a machine-learning model 624 using techniques for development of linear regression models. Linear regression models may include ordinary least squares regression, which aims to minimize the square of the difference between predicted outcomes and actual outcomes according to an appropriate norm for measuring such a difference (e.g. a vector-space distance norm); coefficients of the resulting linear equation may be modified to improve minimization. Linear regression models may include ridge regression methods, where the function to be minimized includes the least-squares function plus term multiplying the square of each coefficient by a scalar amount to penalize large coefficients. Linear regression models may include least absolute shrinkage and selection operator (LASSO) models, in which ridge regression may be combined with multiplying the least-squares term by a factor of 1 divided by double the number of samples. Linear regression models may include a multi-task lasso model wherein the norm applied in the least-squares term of the lasso model may be the Frobenius norm amounting to the square root of the sum of squares of all terms. Linear regression models may include the elastic net model, a multi-task elastic net model, a least angle regression model, a LARS lasso model, an orthogonal matching pursuit model, a Bayesian regression model, a logistic regression model, a stochastic gradient descent model, a perceptron model, a passive aggressive algorithm, a robustness regression model, a Huber regression model, or any other suitable model that may occur to persons skilled in the art upon reviewing the entirety of this disclosure. Linear regression models may be generalized in an embodiment to polynomial regression models, whereby a polynomial equation (e.g. a quadratic, cubic or higher-order equation) providing a best predicted output/actual output fit may be sought; similar methods to those described above may be applied to minimize error functions, as will be apparent to persons skilled in the art upon reviewing the entirety of this disclosure.

Continuing to refer to FIG. 6, machine-learning algorithms may include, without limitation, linear discriminant analysis. Machine-learning algorithm may include quadratic discriminate analysis.

With continued reference to FIG. 6, an “objective function,” as used in this disclosure, is a mathematical function with a solution set including a plurality of data elements to be compared. Mixer may compute a score, metric, ranking, or the like, associated with each performance prognoses and candidate transfer apparatus and select objectives to minimize and/or maximize the score/rank, depending on whether an optimal result may be represented, respectively, by a minimal and/or maximal score; an objective function may be used by mixer to score each possible pairing. At least an optimization problem may be based on one or more objectives, as described below. Mixer may pair a candidate transfer apparatus, with a given combination of performance prognoses, that optimizes the objective function. In various embodiments solving at least an optimization problem may be based on a combination of one or more factors. Each factor may be assigned a score based on predetermined variables. In some embodiments, the assigned scores may be weighted or unweighted. Solving at least an optimization problem may include performing a greedy algorithm process, where optimization may be performed by minimizing and/or maximizing an output of objective function. A “greedy algorithm” is defined as an algorithm that selects locally optimal choices, which may or may not generate a globally optimal solution. For instance, mixer may select objectives so that scores associated therewith are the best score for each goal. For instance, in non-limiting illustrative example, optimization may determine the pitch moment associated with an output of at least a propulsor based on an input.

With continued reference to FIG. 6, at least an optimization problem may be formulated as a linear objective function, which mixer may optimize using a linear program such as without limitation a mixed-integer program. A “linear program,” as used in this disclosure, is a program that optimizes a linear objective function, given at least a constraint; a linear program maybe referred to without limitation as a “linear optimization” process and/or algorithm. For instance, in non-limiting illustrative examples, a given constraint might be torque limit, and a linear program may use a linear objective function to calculate maximum output based on the limit. In various embodiments, mixer may determine a set of instructions towards achieving a user's goal that maximizes a total score subject to a constraint that there are other competing objectives. A mathematical solver may be implemented to solve for the set of instructions that maximizes scores; mathematical solver may be implemented on mixer and/or another device in flight control system, and/or may be implemented on third-party solver. At least an optimization problem may be formulated as nonlinear least squares optimization process. A “nonlinear least squares optimization process,” for the purposes of this disclosure, is a form of least squares analysis used to fit a set of m observations with a model that is non-linear in n unknown parameters, where m is greater than or equal to n. The basis of the method is to approximate the model by a linear one and to refine the parameters by successive iterations. A nonlinear least squares optimization process may output a fit of signals to at least a propulsor. Solving at least an optimization problem may include minimizing a loss function, where a “loss function” is an expression an output of which a ranking process minimizes to generate an optimal result. As a non-limiting example, mixer may assign variables relating to a set of parameters, which may correspond to score components as described above, calculate an output of mathematical expression using the variables, and select an objective that produces an output having the lowest size, according to a given definition of “size,” of the set of outputs representing each of plurality of candidate ingredient combinations; size may, for instance, included absolute value, numerical size, or the like. Selection of different loss functions may result in identification of different potential pairings as generating minimal outputs.

Referring now to FIG. 7, an embodiment of an electric aircraft 700 is presented. Still referring to FIG. 7, electric aircraft 700 may include a vertical takeoff and landing aircraft (eVTOL). As used herein, a vertical take-off and landing (eVTOL) aircraft may be one that can hover, take off, and land vertically. An eVTOL, as used herein, may be an electrically powered aircraft typically using an energy source, of a plurality of energy sources to power the aircraft. In order to optimize the power and energy necessary to propel the aircraft. eVTOL may be capable of rotor-based cruising flight, rotor-based takeoff, rotor-based landing, fixed-wing cruising flight, airplane-style takeoff, airplane-style landing, and/or any combination thereof. Rotor-based flight, as described in this disclosure, may be where the aircraft generated lift and propulsion by way of one or more powered rotors connected with an engine, such as a “quad copter,” multi-rotor helicopter, or other vehicle that maintains its lift primarily using downward thrusting propulsors. Fixed-wing flight, as described in this disclosure, may be where the aircraft may be capable of flight using wings and/or foils that generate life caused by the aircraft's forward airspeed and the shape of the wings and/or foils, such as airplane-style flight. Control forces of the aircraft are achieved by conventional elevators, ailerons and rudders during fixed wing flight. Roll and Pitch control forces on the aircraft are achieved during transition flight by increasing and decreasing torque, and thus thrust on the four lift fans. Increasing torque on both left motors and decreasing torque on both right motors leads to a right roll, for instance. Likewise, increasing the torque on the front motors and decreasing the torque on the rear motors leads to a nose up pitching moment. Clockwise and counterclockwise turning motors torques are increased and decreased to achieve the opposite torque on the overall aircraft about the vertical axis and achieve yaw maneuverability.

With continued reference to FIG. 7, a number of aerodynamic forces may act upon the electric aircraft 700 during flight. Forces acting on an electric aircraft 700 during flight may include, without limitation, thrust, the forward force produced by the rotating element of the electric aircraft 700 and acts parallel to the longitudinal axis. Another force acting upon electric aircraft 700 may be, without limitation, drag, which may be defined as a rearward retarding force which may be caused by disruption of airflow by any protruding surface of the electric aircraft 700 such as, without limitation, the wing, rotor, and fuselage. Drag may oppose thrust and acts rearward parallel to the relative wind. A further force acting upon electric aircraft 700 may include, without limitation, weight, which may include a combined load of the electric aircraft 700 itself, crew, baggage, and/or fuel. Weight may pull electric aircraft 700 downward due to the force of gravity. An additional force acting on electric aircraft 700 may include, without limitation, lift, which may act to oppose the downward force of weight and may be produced by the dynamic effect of air acting on the airfoil and/or downward thrust from the propulsor of the electric aircraft. Lift generated by the airfoil may depend on speed of airflow, density of air, total area of an airfoil and/or segment thereof, and/or an angle of attack between air and the airfoil. For example, and without limitation, electric aircraft 700 are designed to be as lightweight as possible. Reducing the weight of the aircraft and designing to reduce the number of components may be essential to optimize the weight. To save energy, it may be useful to reduce weight of components of an electric aircraft 700, including without limitation propulsors and/or propulsion assemblies. In an embodiment, the motor may eliminate need for many external structural features that otherwise might be needed to join one component to another component. The motor may also increase energy efficiency by enabling a lower physical propulsor profile, reducing drag and/or wind resistance. This may also increase durability by lessening the extent to which drag and/or wind resistance add to forces acting on electric aircraft 700 and/or propulsors.

Referring still to FIG. 7, aircraft may include at least a vertical propulsor 704 and at least a forward propulsor 708. A forward propulsor may be a propulsor that propels the aircraft in a forward direction. Forward in this context may be not an indication of the propulsor position on the aircraft; one or more propulsors mounted on the front, on the wings, at the rear, etc. A vertical propulsor may be a propulsor that propels the aircraft in an upward direction; one of more vertical propulsors may be mounted on the front, on the wings, at the rear, and/or any suitable location. A propulsor, as used herein, may be a component or device used to propel a craft by exerting force on a fluid medium, which may include a gaseous medium such as air or a liquid medium such as water. At least a vertical propulsor 704 may be a propulsor that generates a substantially downward thrust, tending to propel an aircraft in a vertical direction providing thrust for maneuvers such as without limitation, vertical take-off, vertical landing, hovering, and/or rotor-based flight such as “quadcopter” or similar styles of flight.

With continued reference to FIG. 7, at least a forward propulsor 708 as used in this disclosure may be a propulsor positioned for propelling an aircraft in a “forward” direction; at least a forward propulsor may include one or more propulsors mounted on the front, on the wings, at the rear, or a combination of any such positions.

Forces acting on an aircraft 700 during flight may include thrust, the forward force produced by the rotating element of the aircraft 700 and acts parallel to the longitudinal axis. Drag may be defined as a rearward retarding force which may be caused by disruption of airflow by any protruding surface of the aircraft 700 such as, without limitation, the wing, rotor, and fuselage. Drag may oppose thrust and acts rearward parallel to the relative wind. Another force acting on aircraft 700 may include weight, which may include a combined load of the aircraft 700 itself, crew, baggage and fuel. Weight may pull aircraft 700 downward due to the force of gravity. An additional force acting on aircraft 700 may include lift, which may act to oppose the downward force of weight and may be produced by the dynamic effect of air acting on the airfoil and/or downward thrust from at least a propulsor.

A propulsor, as used herein, may be a component or device used to propel a craft by exerting force on a fluid medium, which may include a gaseous medium such as air or a liquid medium such as water. In an embodiment, when a propulsor twists and pulls air behind it, it will, at the same time, push an aircraft forward with an equal amount of force. The more air pulled behind an aircraft, the greater the force with which the aircraft may be pushed forward. Propulsor may include any device or component that consumes electrical power on demand to propel an electric aircraft in a direction or other vehicle while on ground or in-flight.

With continued reference to FIG. 7, in an embodiment, at least a portion of the aircraft may include a propulsor, the propulsor may include a propeller, a blade, or any combination of the two. The function of a propeller may be to convert rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards.

The blade pitch of the propellers may, for example, be fixed, manually variable to a few set positions, automatically variable (e.g. a “constant-speed” type), or any combination thereof. In an embodiment, propellers for an aircraft are designed to be fixed to their hub at an angle similar to the thread on a screw makes an angle to the shaft; this angle may be referred to as a pitch or pitch angle which will determine the speed of the forward movement as the blade rotates.

With continued reference to FIG. 7, aircraft 700 trajectory is manipulated by one or more control surfaces and propulsors working alone or in tandem consistent with the entirety of this disclosure, hereinbelow. Pitch, roll, and yaw may be used to describe an aircraft's attitude and/or heading, as they correspond to three separate and distinct axes about which the aircraft may rotate with an applied moment, torque, and/or other force applied to at least a portion of an aircraft. “Pitch”, for the purposes of this disclosure refers to an aircraft's angle of attack, that is the difference between the aircraft's nose and the horizontal flight trajectory. For example, an aircraft pitches “up” when its nose is angled upward compared to horizontal flight, like in a climb maneuver. In another example, the aircraft pitches “down”, when its nose is angled downward compared to horizontal flight, like in a dive maneuver. When angle of attack is not an acceptable input to any system disclosed herein, proxies may be used such as pilot controls, remote controls, or sensor levels, such as true airspeed sensors, pitot tubes, pneumatic/hydraulic sensors, and the like. “Roll” for the purposes of this disclosure, refers to an aircraft's position about its longitudinal axis, that is to say that when an aircraft rotates about its axis from its tail to its nose, and one side rolls upward, like in a banking maneuver. “Yaw”, for the purposes of this disclosure, refers to an aircraft's turn angle, when an aircraft rotates about an imaginary vertical axis intersecting the center of the earth and the fuselage of the aircraft. “Throttle”, for the purposes of this disclosure, refers to an aircraft outputting an amount of thrust from a propulsor. Pilot input, when referring to throttle, may refer to a pilot's desire to increase or decrease thrust produced by at least a propulsor. More than one propulsor may be required to adjust torques to accomplish the command to change pitch and yaw, mixer would take in the command and allocate those torques to the appropriate propulsors consistent with the entirety of this disclosure. One of ordinary skill in the art, after reading the entirety of this disclosure, will appreciate the limitless combination of propulsors, flight components, control surfaces, or combinations thereof that could be used in tandem to generate some amount of authority in pitch, roll, yaw, and lift of an electric aircraft consistent with this disclosure.
